Presentation Title Factors to Consider when Designing Aluminium Alloys for Increased Scrap Usage

On-Site Speaker (Planned) Luca Montanelli
Abstract Scope For a significant shift in alloy design to happen, the aluminium alloy industry needs to explore a broader range of compositional and processing dimensions. The proposed project will investigate unexplored regions of the compositional space to guide the design of new alloys, especially where opportunities are present to improve recyclability. To achieve this, a blending model will be optimised over compositional space to inform alloy compositions that enable higher quantities of scrap use. Blending models inform on the scrap usage of a candidate alloy when it is set in a predetermined market landscape. Due to their computational cost, machine learning optimisation methods such as Bayesian optimisation will be employed to focus the design process. The optimisation will be subject to constraints that are based on compositions, phase combinations, and relevant properties to ensure that the alloys not only maximise amount of scrap use but also meet technical requirements.
